You should use the setting functions to access settings, not direct access to the object. Direct object access was deprecated in 3.0.

I would expect that if the user explicitly set the etag option to res.sendFile, it would not be overwritten by the setting.

Please add a test that checks the behavior when someone sets the etag setting to strong, weak, or a custom function.

var app = express();

app.disable('etag');
app.use(function (req, res) {
res.sendFile(path.resolve(fixtures, 'name.txt'));
});

request(app)
.get('/')
.end(function(err, res) {
if (err) {
return done(err);
}
assert.equal('etag' in res.headers, false);
done();
});
